I think the real test is going to be on DSOs that are visible but you can
barely make out structure in with your aperture. Will two eyes bring out at
least as much structure with a more pleasing view, or give up some of the
fainter details for a more pleasing view of the brighter ones ... Of course
more aperture will fix this too ...

Hello, Rich,
Interesting post. So binoviewers are not as good on DSOs as on the
moon and
planets.

Hi Bill,

Depends on who you ask, I guess. I use binoviewers for everything. I
know
I'm losing .2 mag, but I get a 3d effect that is mesmerizing and see more
subtle detail more easily. Nothing in the cyclops world can give me the
view I had of M42 on Tues morning with the binoviewers at 69x and a 1 deg
TFOV. BUT (and this is a big but that is strictly me. Others might
say
the same thing, still others will say that this is bunk. That's ok. I
won't even begin to argue about what they see. But, I cannot make a
blanket
statement that binoviewers are not as good on deep sky. For me, they hold
the same benefits for deep sky as they do for the other stuff. I would
sooner buy a bigger telescope (or move to a darker location) to make up
for
the light loss than switch back to cyclops mode.

I am not argueing, just adding to the database. I may be biased

Clear skies,

TOm
